of Pittsburgh, in the county of Alleghenyy and State of Pennsylvania, have invented a new and useful Improvement in Built-Up Truck Side Framesgand I do hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to improvements 1n truck side frames and is particularly concerned with the construction of a side frame in which all parts including the pedestal are formed of rolled sections of steel. The 0bject ofthe invention is the production of a side frameV of great strength in proportion to its weight, one in which the parts may be very easily and strongly assembled. A further object is to secure a very material reduction in the cost of manufacture, both in the production of the parts of the frame, and

also in the labor of assembling.

With these objects in view the invention Vconsists in constructions and arrangements of parts, preferred embodiments of which are illustrated in the accompanying drawings, in which Figure 1 is a side elevation of a side frame embodying the improvements; Fig. 2 is a longitudinal vertical section of said frame; Fig.`3 is a plan view; Fig. 11 is a sectional view on the linea-1, Fig. 1; Fig. 5 is a sectional view on the line 5-5 Fig. 1; Fig. 6 is a fragmentary perspective view illustrating forms of rolled sections lwhich may be employed as the compression and tension members of theframe, respectively. Figs. 7, 8, 9, and 10 are views similar to Fig. 6 illustrating modified forms of sections which may be so employed. Figs. 11 and 12 illustrate respectively compression and tension members of the same general shape in which parts of the compression member are eut away to permit the proper assembling of the two members of the frame. Fig. 13 illustrates a further modification which permits a change in the form of the truck pedestal hereinafter described.

In one of the preferred forms of the invention in so far as I am able to determine the same at this time, the rolled sections employed as the compression and tension members respectively are of the form shown in Fig. 10 in which the compression member consists of a section of flanged channel form, having the web 1, the side walls 2, 2, and the lateral flanges 3, 3. Such a rolled section may be produced in a manner well known to those skilled in the art of metal rolling. The tension member consists of a rolled section having the base web 4E extend' ing laterally into the flanges 5, 5, the side walls 6, 6, and the upper flanges 7, 7. The side frame illustrated in Figs. 1 to 5 inclusive, is constructed of sectionssuch as those just described and shown in Fig. 10. It will be noticed from Fig. 10 that the compression member consists of the simple channel sections.12-2, of a width to lit snugly within the channel 4-6-6 of the tension member and the flanges 3 3 of the compression section are riveted to the flanges 7, 7 of the tension member as at S. The compression and tension members are bent to the form shown in Figs. 1 and 2 and are thus spaced apart to receive the pedestal. This pedestal as shown in Figs. 1, 2, 4 and 5 is formed of a simple rolled channel section having the base web 9 and the flanges 10, 10, and is bent into the pedestal section as illustrated in Figs. 1 and 2. This channeled ped estal section is of such width that its flanges 10-10` lit exactly within the side walls 6 6 of the tension member as illustrated in Fig. 4c and saidV flanges 10 and the side walls G are riveted together as at 11. Inasmuch as the pedestal section in the form of the invention now being described is of the saine width as the compression section, the flanges 10-10 at the upper` side of the pedestal section are expanded as shown at 12-12 so that said flanges may closely embrace the side walls 2 of the compression member and are secured thereto by rivets 10. Referring again to Fig. l it will be seen that the flanges 7 7 of the tension member and the bottom weh 9 of the pedestal, together form a flat face or foundation for the reception of the spring base plank 13 which extends from one side frame to the other in the usual manner and this spring plank as will be seen from Figs. 1 and 2 may be formed of a rolled section having the flanges 14-141, which not only form proper housings for the lower ends of the bolster springs, but also serve to strengthen the spring support.

From the peculiar construction of the compression and tension sections as above described, it will be seen that an especially strong structure of side frame is produced and the strength is properly distributed to resist the various strains brought to bear on the frame. For example, the box like llO structure of the tension member formed by said member and the lower portion of the pedestal section as shown in Fig. 4f. provides an especially strongstructure for receiving the thrust of the bolster springs 15. Again the-broad web 4 with its flanges 5 5 of the tension member forms a strong construction for the reception of the pillar bolts 1G of the journal box 17 and for the journal boxes themselves and this journalbox bearing is reinforced by the base web 1 of the c0mpression member or section.

Considering the compression and tension members in their simplest aspect, it will be seen that they consist essentially of continuous channel members, the ends of one fitting within the ends of the other, thus affording the most powerful construction to resist lateral as well as vertical strains. It is apparent, therefore, that in its simplest aspect, this invention contemplates the use of simple channel sections for the compression and tension members. These simple channel members may be developed by additions of various arrangements and constructions of flanges for reinforcement and for providing proper bearings for the bolster springs and for the journal boxes.

As illustrating the various forms which the compression and tension members or sections may take, reference is made to F 5 to 9 inclusive and 11, 12, and 13. Fig. 10, as before stated, illustrates a development of these sections which is 'employed in the preferred form of the invention, illustrated in Figs. 1 to 5 inclusive. In Fig. 6 the compression member is formed from a channel section having the bottom web 18 and the side walls 19, 19. The tension member comprises the bottom web 20 and the side walls 21, 21. In Fig. 7 the compression member may be the same as that shown in Fig. G and the tension member also the same as illustrated in Fig. 6 with the addition of the flanges 122-22. In Fig. 8 the tension member is that same as that shown in Fig. 7, while the compression member is likewise the same with the addition of the flanges 23. In Fig. 9 the compression member is like that in Fig. 7 and the tension member like the form Fig. 10. In Figs. 11 and 12, the two sections which form the compression and tension members are of the same form, the tension member consisting of a section similar to that shown in Fig. 10 and having the web 4f, the base flanges 5 5 and the upper flanges 7-7. The compression member .comprises a channel portion consisting of the web 211, the side walls 25, 25, and the upper flanges 26, 26. As shown in Fig. 11 which illustrates the compression member, the web 4l is expanded into flanges 27, 27, which are cut back adjacent the ends of the section to the point 27 to permit the channel portion 241, 25, 25 to fit or nest within the channel shaped ends of the tension member. In the construction illustrated in Fig. 13 it will be seen that the channel portion 28, 28-2,8 may be somewhat narrower than the space between the side walls 29-29 of the channel portion of the tension member, so that the side flanges 10 of the pedestal channel section may in their normal position embrace the side walls 28 of the compression member and likewise fit snugly within said walls 29 of the tension member, thus avoiding the necessity of expanding flanges along the upper side of the pedestal member.

By reason of the fact that the compression and tension members and the pedestal section may be riveted together through their respective flanges or side walls, it will be seen that all of the rivets of the structure may bein shear instead of in tension, thereby securing the greatest possible strength in the junctures of these parts. A

From the manner of forming this compression section and afterward cutting away the same as just described, it will be seen that in this form of the invention also, we retain the simple channel shape of the section at the ends which engage or are nested within the ends of the tension member, and

moreover, these channel shaped ends of the compression member may fit snugly within the side walls of the tension member while at the same time the depending flanges at t-he center of the compression member may be at a less distance apart and thus engage within the flanges of the pedestal without expanding the pedestal flanges at the upper side.

While I have herein described preferred embodiments of my invention, and have illustrated possible modifications not only of the sections from which the compression and tension members respectively may be formed, but also dierences in relative arrangement of the parts, it is to be understood that the invention may be still further modi-- fied within the scope of the appended claims.
